This invention relates to new anduseful' improvements in brackets, serving as a sup-m port for scaffolds, and the said device has been especially adapted for use in connection with the glazing, painting and cleaning of metalrame casemen win ows ina s l f t d J smuch a tie construction has been effected in such a manner as to permit the closing of windowsover the brackets, thereby giving the worker on the scaffold perfect freedom of movements. A wider and more comprehensive use may,

however, be derived from employing the said brackets as a supporting means tor scatfolds generally, for instance, when repairing and painting the outer surface of a wall- As the construction of the device is extremely simple,

the cost of manufacturing should be proportionately low.

With the above and other objects in view, this invention consistsof the novel features of construction, combination and' arrangements of parts, hereinafter fully described, claimed and illustrated in the accompanying drawing forming parts of this specification,

and in which similar characters of reference indicate corresponding parts in all views, and

in which:

Figure 1 is a side elevational view of my device; Fig. 2 is a top plan view of same;

Fig. 3 shows a modification of my device for wardly'projecting bar 17 is solidlyattached to the outside, at the upper corner of said frame, for the purpose of serving as a retaining means for the scaffold planks, which in some instances, when occasion requires, may be placed on top of the said bracket members.

In this connection it may be pointed out, that round or square block 28. "The latter may at least two bracketsiwould naturally be em ployed for thesupport of a scaffold, while -a greater number of brackets be employed according to the occasion.

The'bar member 12'has at one end a piece 18 projectingoutside the frame proper, and serving as a support for a slidable hook-member 19, as shown in Fig. 1. The said hookmember consists of a bar, having a shape similar to those'constituting the frame proper, with the exception that the said hook-member 19, is atone end provided with a few angular bends, of which the last terminates in a hook orcatch20j 1 v The said catch 20 is especially adapted to engage the horizontally positioned edge-por tion 21 that forms an integral'and'centralv part of all steel trame casement windows, thereby securing the said bracketsin a safe and dependable suspended position, ready to receive the scaffold planks 22.

The said hook-member may be adj usted'in length to correspond to the width of the window sill, etc., such adjustments-being accomplished by providing the said member 19 with a couple of recessed'portions 23 and 2d adapted to receive set screws 25 of the bar 12, thus securing the two bars 19' and 12 with-its elongated end portion 18-together,- while a wooden block l6'is arranged, asshown in Fig. 1, to lessen the strain on the said bars. 7

In order to lend substantial supportto the said bracket, a bolt-member 26 has been adjustably mounted upon thelower end of they bar 13,'thesaid bolt being formed with screw threaded body, fitted to engage a correspondingly threaded opening27 in the said bar 13. The said bolt is further upon its end formed with a buffer in the shape of a small,

0 'inorder not to damage the wall ofa building, haveitsend-surface covered with a rubber or felt pad, as shown by numeral 29 in Figs. 1 and 3; The relative connection of the said bolt and block is of the well known kind, 95 where the endpiece of the bolt may turn freely within the said block member.

'It is thus evident that in actual operation, all that is necessary in order to provide a suit- "ably placed, and perfectly safe scaffold, 1

In order, however, to provide for a greater latitude of use,.an extensionmember, 31, toube attached to each,bracket,has beenshown in Fig. 3. The said extension member comprises 19 a three sided frame bent at'right angles and adapted to be snapped-onto theilower por-- tion off the bracket 10. The said extension member has the usual supporting and buflin-g means, indicated by the numeral26.
